BACKGROUND OF THE INVENTION Field of the Invention

The disclosure relates to the field of machine learning, more particularly to model improvement using biases contained in data distributed across multiple devices.

Discussion of the State of the Art

In traditional machine learning, data is generally gathered and processed at a central location. The gathered data may then be used to train models. However, gatherable data, through means such as web scraping, or news aggregation, may be relatively narrow in scope compared to what is stored on devices, for instance a person's mobile device or crime data from a local police station. This data may seldom leave the devices it is stored on due to the possibility of it containing sensitive data, and also the bandwidth required to transfer the data may be extensive.

Another possible problem with data stored on distributed devices is that the data may contain biases that may not be conducive for use to train a general-use model. These biases, for example, may exist on devices from certain regions, various age groups, or various ethnicities. However, there may be valuable information that may be gleaned from biases contained within data, and may be applied to models that utilizes such specialized data.

What is needed is a system in which biases within data stored on distributed devices may be identified and used to improve a specialized model, while also maintaining privacy for the owner of the data. Such a system would also need a method of improving the model with potentially vast amounts of data while keeping bandwidth usage as low as possible.

SUMMARY OF THE INVENTION

Accordingly, the inventor has conceived a system and method for improving a regionalized distributable model with biases contained in distributed data.

In a preferred embodiment, a model source may serve instances of a variety of distributable models: a generalized model in which data used to train it has had biases weighted and corrected, and also a bias-specific model in which biases are utilized. The instances are served to distributed devices, where they may be trained by the devices. The devices each generate an update report, which is transferred back to the model source, where the model source may use the report to improve the main models.

In one aspect of the invention, a system for improving a distributable model with biases contained in distributed data is provided, comprising a network-connected distributable model source comprising a memory, a processor, and a plurality of programming instructions stored in the memory thereof and operable on the processor thereof, wherein the programmable instructions, when operating on the processor, cause the processor to serve instances of a plurality of distributable models; and a directed computation graph module comprising a memory, a processor, and a plurality of programming instructions stored in the memory thereof and operable on the processor thereof, wherein the programmable instructions, when operating on the processor, cause the processor to receive at least an instance of at least one of the distributable models from the network-connected computing system, create a cleansed dataset from data stored in the memory based at least in part by biases contained within the data stored in memory, train the instance of the distributable model with the cleansed dataset, and generate an update report based at least in part by updates to the instance of the distributable model.

In another embodiment of the invention, at least a portion the cleansed dataset is data that has had sensitive information removed. In another embodiment of the invention, at least a portion of the update report is used by the network-connected distributable model source to improve the distributable model. In another embodiment of the invention, at least a portion of the biases contained within the data stored in memory is based on geography.

Particular features of one or more of the aspects described herein may be described with reference to one or more particular aspects or figures that form a part of the present disclosure, and in which are shown, by way of illustration, specific arrangements of one or more of the aspects. It should be appreciated, however, that such features are not limited to usage in the one or more particular aspects or figures with reference to which they are described. The present disclosure is neither a literal description of all arrangements of one or more of the aspects nor a listing of features of one or more of the aspects that must be present in all arrangements.

Headings of sections provided in this patent application and the title of this patent application are for convenience only, and are not to be taken as limiting the disclosure in any way.

Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more communication means or intermediaries, logical or physical.

A description of an aspect with several components in communication with each other does not imply that all such components are required. To the contrary, a variety of optional components may be described to illustrate a wide variety of possible aspects and in order to more fully illustrate one or more aspects. Similarly, although process steps, method steps, algorithms or the like may be described in a sequential order, such processes, methods and algorithms may generally be configured to work in alternate orders, unless specifically stated to the contrary. In other words, any sequence or order of steps that may be described in this patent application does not, in and of itself, indicate a requirement that the steps be performed in that order. The steps of described processes may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to one or more of the aspects, and does not imply that the illustrated process is preferred. Also, steps are generally described once per aspect, but this does not mean they must occur once, or that they may only occur once each time a process, method, or algorithm is carried out or executed. Some steps may be omitted in some aspects or some occurrences, or some steps may be executed more than once in a given aspect or occurrence.

When a single device or article is described herein, it will be readily apparent that more than one device or article may be used in place of a single device or article. Similarly, where more than one device or article is described herein, it will be readily apparent that a single device or article may be used in place of the more than one device or article.

The functionality or the features of a device may be alternatively embodied by one or more other devices that are not explicitly described as having such functionality or features. Thus, other aspects need not include the device itself.

Techniques and mechanisms described or referenced herein will sometimes be described in singular form for clarity. However, it should be appreciated that particular aspects may include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. Process descriptions or blocks in figures should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process. Alternate implementations are included within the scope of various aspects in which, for example, functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art.

Conceptual Architecture

FIG. 1 is a diagram of an exemplary architecture of a business operating system 100 according to an embodiment of the invention. Client access to system 105 for specific data entry, system control and for interaction with system output such as automated predictive decision making and planning and alternate pathway simulations, occurs through the system's distributed, extensible high bandwidth cloud interface 110 which uses a versatile, robust web application driven interface for both input and display of client-facing information and a data store 112 such as, but not limited to MONGODB™, COUCHDB™, CASSANDRA™ or REDIS™ depending on the embodiment. Much of the business data analyzed by the system both from sources within the confines of the client business, and from cloud based sources 107, public or proprietary such as, but not limited to: subscribed business field specific data services, external remote sensors, subscribed satellite image and data feeds and web sites of interest to business operations both general and field specific, also enter the system through the cloud interface 110, data being passed to the connector module 135 which may possess the API routines 135 a needed to accept and convert the external data and then pass the normalized information to other analysis and transformation components of the system, the directed computational graph module 155, high volume web crawler module 115, multidimensional time series database 120 and a graph stack service 145. Directed computational graph module 155 retrieves one or more streams of data from a plurality of sources, which includes, but is not limited to, a plurality of physical sensors, network service providers, web based questionnaires and surveys, monitoring of electronic infrastructure, crowd sourcing campaigns, and human input device information. Within directed computational graph module 155, data may be split into two identical streams in a specialized pre-programmed data pipeline 155 a, wherein one sub-stream may be sent for batch processing and storage while the other sub-stream may be reformatted for transformation pipeline analysis. The data may be then transferred to a general transformer service module 160 for linear data transformation as part of analysis or the decomposable transformer service module 150 for branching or iterative transformations that are part of analysis. Directed computational graph module 155 represents all data as directed graphs where the transformations are nodes and the result messages between transformations edges of the graph. High-volume web crawling module 115 may use multiple server hosted preprogrammed web spiders which, while autonomously configured, may be deployed within a web scraping framework 115 a of which SCRAPY™ is an example, to identify and retrieve data of interest from web based sources that are not well tagged by conventional web crawling technology. Multiple dimension time series data store module 120 may receive streaming data from a large plurality of sensors that may be of several different types. Multiple dimension time series data store module 120 may also store any time series data encountered by system 100 such as, but not limited to, environmental factors at insured client infrastructure sites, component sensor readings and system logs of some or all insured client equipment, weather and catastrophic event reports for regions an insured client occupies, political communiques and/or news from regions hosting insured client infrastructure and network service information captures (such as, but not limited to, news, capital funding opportunities and financial feeds, and sales, market condition), and service related customer data. Multiple dimension time series data store module 120 may accommodate irregular and high-volume surges by dynamically allotting network bandwidth and server processing channels to process the incoming data. Inclusion of programming wrappers 120 a for languages—examples of which may include, but are not limited to, C++, PERL, PYTHON, and ERLANG™—allows sophisticated programming logic to be added to default functions of multidimensional time series database 120 without intimate knowledge of the core programming, greatly extending breadth of function. Data retrieved by multidimensional time series database 120 and high-volume web crawling module 115 may be further analyzed and transformed into task-optimized results by directed computational graph 155 and associated general transformer service 160 and decomposable transformer service 150 modules. Alternately, data from the multidimensional time series database and high-volume web crawling modules may be sent, often with scripted cuing information determining important vertices 145 a, to graph stack service module 145 which, employing standardized protocols for converting streams of information into graph representations of that data, for example open graph internet technology (although the invention is not reliant on any one standard). Through the steps, graph stack service module 145 represents data in graphical form influenced by any pre-determined scripted modifications 145 a and stores it in a graph-based data store 145 b such as GIRAPH™ or a key-value pair type data store REDIS™, or RIAK™, among others, any of which are suitable for storing graph-based information.

Results of the transformative analysis process may then be combined with further client directives, additional business rules and practices relevant to the analysis and situational information external to the data already available in automated planning service module 130, which also runs powerful information theory-based predictive statistics functions and machine learning algorithms 130 a to allow future trends and outcomes to be rapidly forecast based upon the current system derived results and choosing each a plurality of possible business decisions. Then, using all or most available data, automated planning service module 130 may propose business decisions most likely to result in favorable business outcomes with a usably high level of certainty. Closely related to the automated planning service module 130 in the use of system-derived results in conjunction with possible externally supplied additional information in the assistance of end user business decision making, action outcome simulation module 125 with a discrete event simulator programming module 125 a coupled with an end user-facing observation and state estimation service 140, which is highly scriptable 140 b as circumstances require and has a game engine 140 a to more realistically stage possible outcomes of business decisions under consideration, allows business decision makers to investigate the probable outcomes of choosing one pending course of action over another based upon analysis of the current available data.

FIG. 2 is a block diagram of an exemplary system 200 that may be used for improving a distributable model with data distributed amongst a plurality of devices with a business operating system according to various embodiments of the invention. System 200 comprises a distributable model source 201, and a plurality of electronic devices 220[a-n]. Model source 201 may comprise a distributable model 205, a local data store 210, and a synthetic data store 215; while the electronic devices each may have an instanced model 221[a-n], and device data 222[a-n]. Electronic devices 220[a-n] may be any type of computerized hardware commonly used in the art, including, but not limited to, desktop computers, laptops, mobile devices, tablets, and computer clusters. For simplicity, the discussions below regarding system 200 will be from the perspective of a singular device 220 a, which comprises instanced model 221 a and device data 222 a. It should be understood that devices 220[a-n] may operate independently, and in a manner similar to device 220 a.

Model source 201 may be configured to serve an instanced copy of distributable model 205 to device 220 a, and may be any type of computerized hardware used in the art configured to use business operating system 100, and may communicate with connected devices via directed computation graph data pipeline 155 a which may allow incoming and outgoing data to be processed on-the-fly. Distributable model 205 may be a model conventionally used in the art in machine learning, or it may be a specialized model that has been tuned to more efficiently utilize training data that has been distributed amongst various devices while still being able to be trained through traditional machine learning methods. Local data 210 may comprise data that was been previously stored, or data is that in the process of being stored, for example, data that is presently being gathered through monitoring of other systems. Synthetic data 215 may be data that has been intelligently and/or predictively generated to fit the context of a model, and is generally based on real-world trends and events. Examples of synthetic data 215 may include data that has been gathered from running computer simulations; data that has been generated using the predictive simulation functions of business operating system 100 with previously stored data, and current trends; or with the use of other specialized software, such as SNORKEL. Local data 210 and synthetic data 215 may be used by model source 201 as training data for distributable model 205. Although illustrated in FIG. 2 as stored within model source 201, it will be appreciated by one skilled in the art that local data 210 and synthetic data 215 may originate from external systems, and provided to model source 201 through some means such as, for example, the internet or a local area network connection.

In system 200, device 220 a may connect to model source 201 via a network connection, such as through the internet, local area network, virtual private network, or the like, where device 220 a may be provided an instanced copy of the distributable model 221 a. Device 220 a may then cleanse and sanitize its own data 222 a, and train its instanced model 221 a with the cleansed data. A report based on the updates made to instanced model 221 a is generated on device 220 a, and then transmitted back to model source 201. The report may be used by model source 201 to improve distributable model 205. In a preferred embodiment, devices 220[a-n] may comprise systems configured to use business operating system 100, and utilize its directed computation graph capabilities, amongst other functions, to process the data. However, in some embodiments, hardware for the electronic devices may be, for example, a mobile device or computer system running another operating system. These systems may use specialized software configured to process the data according to established compatibility specifications.

System 200 may also be configured to allow certain biases in the data to remain. Biases such as geographical origin of data may be necessary in some cases to adhere to local laws. For example, some countries may have certain laws in place to prevent import and export of data to and from some other restricted countries. By taking into consideration the bias regarding geographical origin of the data, the bias may be used to classify the incoming update reports. The update reports may then be used to train a geographically-restricted distributable model without including data from other restricted countries, while still including data from non-restricted countries.

To provide another example application, crime reports and data distributed across multiple police municipalities may contain information regarding new trends in crime that may be relevant to crime prediction models. However, this data may contain sensitive non-public information that must stay within that particular municipality. With the system described herein, the data may be scrubbed of sensitive information, used to train an instance of the crime prediction model, and the relevant data may be indirectly integrated into the crime prediction model. Since the actual data does not leave the computer system of that particular municipality, this can be done without any concern of sensitive information leaking out.

It should be understood that electronic devices 220[a-n] do not have to all concurrently be connected to model source 201 at the same time, and any number of devices may be actively connected to, and interacting with model source 201 at a given time. Also, improving of a distributable model, improving of an instanced model, and the back and forth communication may not be running continuously, and may be executed only when required. Furthermore, for simplicity, FIG. 2 illustrates only one instance. However, in practice, system 200 may be a segment of a potentially larger system with multiple distributable model sources; or a distributable model source may store and serve a plurality of distributable models. Electronic devices 220[a-n] are not limited to interacting with just one distributable model source, and may connect with, and interact with, as many distributable model sources as is required.

Since biases contained within the data may be contain valuable information, or grant valuable insight when applied to the right models, it may be prudent to utilize this data for specialized models.

FIG. 3 is a block diagram of an exemplary system 300 that may utilize biases contained within data distributed amongst various sectors to improve a bias-specific distributable model according to various embodiments of the invention. System 300 may comprise a distributable model source 301; and a group of sectors 302, which may comprise a plurality of sectors 325[a-h]. Model source 301 may be a system similar to model source 201 including a source of local data 310 and a source of synthetic data 315 that may be used in an identical fashion; however, model source 301 may serve instances of two different models—a generalized distributable model 305, and a bias-specific distributable model 320. Generalized distributable model 305, may be a model that may be trained with data distributed across various sectors in group 302 wherein the biases within the data has been weighted and corrected, which is similar to distributable model 205. Bias-specific distributable model 320 may be a model in which any of the biases contained within the data from each sector 325[a-n] may be carefully considered.

Each of sectors 325[a-h] may be devices with distributed data, similar to electronic devices 220[a-n] from FIG. 2, that has been assigned a classification, for example, devices within a certain region. However, sectors are not limited to being geographically-based. To provide a few non-geographical examples, sectors 325[a-h] may be devices classified by age groups, income classes, interest groups, or the like. Devices within any of sectors 325[a-h] may obtain an instance of the generalized distributable model and the bias-specific model. The devices may then train the instanced models with its own stored data that has been processed in a manner such as the method described below in FIG. 7, and ultimately lead to improvements of the generalized model, and bias-specific model.

It should be understood that, similar to system 200 as shown in FIG. 2, the embodiment shown in system 300 shows one possible arrangement of a distributable model source and data sources and chosen for simplicity. In other embodiments, there may be, for example, more or less sectors in a group, there may be several groups of sectors, or there may be multiple models, both generalized and bias-specific. See the discussion for FIG. 4 below for an example that has multiple tiers, with each tier having its own group of sectors.

FIG. 4 is a block diagram of an exemplary hierarchy 400 in which each level may have its own set of distributable models according to various embodiments of the invention. At the highest level of hierarchy 400, there is a global level 405 which may encompass all lower levels of hierarchy 400. Directly beneath global-level 405 may be a plurality of continent-level 410 sectors, which may, in turn, encompass all the levels beneath it. Continuing with the pattern, directly beneath the continent level may be a plurality of country-level 415 sectors, which may have a plurality of state-level or province-level 420 sectors, which leads to county-level 425 sectors, then city-level 430 sectors, and then to neighborhood-level 435 sectors. Each level of sectors may have a system as described in FIG. 3, and have a distributable model specifically for utilizing biases gleaned from data from within the sector distribution on each level, as well as a generalized distributable model with biases weighted and corrected to some extent. Models may also be shared between levels if, for instance, a particular model on one level is applicable to another level. Models and data gathered within a level may not be limited to being used in adjacent levels, for example, data gathered at the county level may also be relevant, with biases weighted and corrected, to global-level models, as well as neighborhood-level models.

For example, a global company may have office of operations spread across the globe. This company may have a global office that manages offices in a subgroup of business regions, for example business regions commonly used such as APAC, America, LATAM, SEA, and the like. These business regions may each have a regional office that manages its own subgroup of countries within these regions. These counties may each have a national office that manages its own subgroup of states/provinces/territories. There may be deeper, more granular subgroups, as shown in FIG. 4, but for the purposes of this example, the deepest level used will be states/provinces/territories.

The global office may have a system configured to use business operating system 100, and may serve two distributable models: a generalized distributable model configured to analyze cleansed data from the distributed business regions on a global scale, and also a bias-specific distributable model that utilizes the biases in the data distributed amongst the business regions. An example of a global model may be a model that predicts effects on the environment or global climate, while a business region-specific model may be a model that predicts business earnings based on regional data, such as, the economy of each region, developing trends in each region, or population of each region. At the next level down, a regional office may serve distributable models to countries within that region: a distributed model for bias-corrected region-wide distributed data, and a distributable bias-based model that utilizes biases within country-level distributed data. The models may be similar to the models served by the global office, but may be more regional and country-centric, for example, regional environment and climate, and country-level business forecasts, respectively. At the next level, and final level for this example, a national office may serve distributable models to states/provinces/territories within that country, similar to the example models in the global and regional levels. The data distributed at the state level may be gathered and used to train these models. It should be noted that the distribution of model is compartmentalized at each level to simplify the example, and does not represent any limitation of the present invention. In other embodiments, for example, a single system in any of the levels may serve all the various models to every level of the hierarchy, or there may be servers outside out of the systems of the global company used in this example that may serve the model.

Detailed Description of Exemplary Aspects

FIG. 5 is a flowchart illustrating a method 500 for cleaning and sanitizing data stored on an electronic device before training an instance of a distributable model according to various embodiments of the invention. At an initial step 505, biases found within the data are identified, and corrected so that the data may be more conducive for usage in a generalized distributable model. Biases may include, but is not limited to, local or regional trends, language or racial trends, and gender trends. The biases are intelligently weighted to provide useful insight without overfitting the data sets. In some embodiments, the bias data may be specially identified and stored to be used on other, more regionalized distributable models. At step 510, in order to maintain privacy of users and systems, the data may be scrubbed of personally identifiable information, and other sensitive information. This information may include banking information, medical history, addresses, personal history, and the like. At step 515, the data, now cleansed and sanitized, may be labeled to be used as training data. At step 520, the data is now appropriately formatted to be used for training an instanced model.

It should be noted that method 500 outlines one method for cleaning and sanitizing data. In other embodiments, some of the steps in method 500 may be skipped, or other steps may be added. Besides being used for training an instanced model, and ultimately improving a distributable model, the data may be processed in a similar fashion to become more generalized and appropriate for transfer for usage in training models belonging to different domains. This allows data that has been previously gathered to be re-used in new models, without the sometimes arduous of regathering data that is specially formatted for the context of a specific domain of the newly created model.

FIG. 6 is a flowchart illustrating a method 600 for improving a distributable model on a device external from the source of the model according to various embodiments of the invention. At an initial step 605, an instance of the distributable model is shared with a device from the distributable model source. At step 610, the data on the device is cleansed and sanitized, one such method is outlined in FIG. 5. At step 615, the data, now in a format suitable for use in training a general-use distributable model, may be used to train the instanced model on the device. At step 620, a report based on updates to the instanced model may be generated, and transferred to the distributable model source. One benefit of generating and transferring a report, as opposed to transferring of the data itself, is that it may be a more efficient approach than transferring all data required to improve a distributable model. Also, since the raw data does not need to leave the device, this method may help further ensure sensitive information is not leaked. At step 625, the report is used by the distributable model source to improve the distributable model.

FIG. 7 is a flowchart illustrating a method 700 for improving a bias-specific and generalized distributable model with data on distributed devices according to various embodiments of the invention. At an initial step 705, a device obtains instances of distributable models from a model source: a generalized distributable model, and a bias-specific distributable model. At step 710, a first dataset is created with data stored on the device that has had biases within the data intelligently identified and processed by business operating system 100 for use with a bias-specific model. At step 715, a second dataset is created with the data stored on the device with biases within the data intelligently weighted and corrected, so that the dataset may be more appropriate for a generalized model. At step 720, the datasets are cleansed and scrubbed of sensitive information. At step 725, the first and second datasets are used to train the instance of their respective models; the first dataset trains the instance of the bias-specific model, and the second dataset trains the instance of the generalized model. At step 730, reports are generated based on updates made to the instances of each model. Following the generation of the reports, the steps are similar to the last steps of method 600, specifically steps 620 and 625. The generated reports are transferred to the model source, and they are each used to improve their respective models.

Examples of program instructions include both object code, such as may be produced by a compiler, machine code, such as may be produced by an assembler or a linker, byte code, such as may be generated by for example a JAVA™ compiler and may be executed using a Java virtual machine or equivalent, or files containing higher level code that may be executed by the computer using an interpreter (for example, scripts written in Python, Perl, Ruby, Groovy, or any other scripting language).

In some aspects, systems may be implemented on a standalone computing system. Referring now to FIG. 9, there is shown a block diagram depicting a typical exemplary architecture of one or more aspects or components thereof on a standalone computing system.

In addition, in some aspects, servers 32 may call external services 37 when needed to obtain additional information, or to refer to additional data concerning a particular call. Communications with external services 37 may take place, for example, via one or more networks 31. In various aspects, external services 37 may comprise web-enabled services or functionality related to or installed on the hardware device itself. For example, in one aspect where client applications 24 are implemented on a smartphone or other electronic device, client applications 24 may obtain information stored in a server system 32 in the cloud or on an external service 37 deployed on one or more of a particular enterprise's or user's premises.

In some aspects, clients 33 or servers 32 (or both) may make use of one or more specialized services or appliances that may be deployed locally or remotely across one or more networks 31. For example, one or more databases 34 may be used or referred to by one or more aspects. It should be understood by one having ordinary skill in the art that databases 34 may be arranged in a wide variety of architectures and using a wide variety of data access and manipulation means. For example, in various aspects one or more databases 34 may comprise a relational database system using a structured query language (SQL), while others may comprise an alternative data storage technology such as those referred to in the art as “NoSQL” (for example, HADOOP CASSANDRA™, GOOGLE BIGTABLE™, and so forth). In some aspects, variant database architectures such as column-oriented databases, in-memory databases, clustered databases, distributed databases, or even flat file data repositories may be used according to the aspect. It will be appreciated by one having ordinary skill in the art that any combination of known or future database technologies may be used as appropriate, unless a specific database technology or a specific arrangement of components is specified for a particular aspect described herein. Moreover, it should be appreciated that the term “database” as used herein may refer to a physical database machine, a cluster of machines acting as a single database system, or a logical database within an overall database management system. Unless a specific meaning is specified for a given use of the term “database”, it should be construed to mean any of these senses of the word, all of which are understood as a plain meaning of the term “database” by those having ordinary skill in the art.

Similarly, some aspects may make use of one or more security systems 36 and configuration systems 35. Security and configuration management are common information technology (IT) and web functions, and some amount of each are generally associated with any IT or web systems. It should be understood by one having ordinary skill in the art that any configuration or security subsystems known in the art now or in the future may be used in conjunction with aspects without limitation, unless a specific security 36 or configuration system 35 or approach is specifically required by the description of any specific aspect.
